Answer:
Part 67) 
and 
Part 68) 
or 
Step-by-step explanation:
Part 67) we know that
The solution of the number line is the interval -------> (-2,3)
All real numbers greater than -2 and less than 3
so
The compound inequality could be
and
"And” indicates that, both statements must be true at the same time
Part 68) we know that
The solution of the number line is the interval (-∞,-1] ∪ [1,∞)
All real numbers less than or equal to -1 or all real numbers greater than or equal to 1
The compound inequality could be
or
"Or” indicates that, as long as either statement is true, the entire compound sentence is true
Answer:
C. 9×3 + 3×2
The area of the figure is 33 in.
Answer:
Explanation:
<u>1. Given vector:</u>
- length: 4.00 mm = magnitude of the vector
- angle: 23.5º north of east = 23.5º from the x-axys (counterclockwise)
<u>2. y-component</u>
The y-component may be determined using the sine ratio, the angle from the x-axys (counterclockwise direction), and the magnitude of the vector.
- sine (23.5º) = y-component / magnitude
- y-component = magnitude × sine (23.5º) = 4.00 mm × sine (23.5º) = 1.59 mm.
Answer:
45
Step-by-step explanation:
When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.
